What is the solution of the system? use the elimination method. -4x+y=-6 8x-2y=14

dybincka [34]3 years ago
3 0

Answer:

There is no solution.

Step-by-step explanation:

-4x+y = -6 rearranged to slope intercept form would be y = 4x-6 because slope intercept form is y = mx+b where m is the slope and b is the y-intercept. Also, when the x has to swap to the other side of the equal sign, it will change from negative to positive, or vise versa. Then, 8x-2y = 14 would be y = 4x-7 because if you divide 8x, -2y, and 14 by -2 in order to isolate your y, the equation would turn into -4x+y = -7. Again, rearrange it to slope intercept form. Now that your equations are both in slope intercept form, you rewrite them without the ys. Which means, 4x-6 = 4x-7. However that is not true. To further explain, you can subtract 4x from each side of the equal sign, leving finally -6 = -7. And that is still not true. Therefore, the final answer would be no solution.

iVinArrow [24]

Answer:

The set of all pages in the book:

S={1, 2, 3, ..., 428}

Step-by-step explanation:

The sample space is the set containing all possible outcomes for the experiment. In this problem, the experiment is stopping at a random page of the textbook, and the sample space is the set of all pages in the book:

S={1, 2, 3, ..., 428}.

The number line between 0 and 1 is partitioned into 6 equal pieces.What fraction of the whole is each piece?
Leno4ka [110]

A fraction is a way to describe a part of a whole. The fraction of the whole is each piece is 1/6.

<h3>What is a Fraction?</h3>

A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.

The number line between 0 and 1 is partitioned into 6 equal pieces. Therefore, a single unit will exist between 0 and 1, which will be divided into six equal parts. Therefore, each fraction will be 1/6 of the unit.

Hence, the fraction of the whole is each piece is 1/6.

Solve - pv + 40 &lt; 65 for v<br> solve 7w - 3r = 15 for r
Katarina [22]

Answer:

v > -25/p

r = -5 +7/3 w

Step-by-step explanation:

- pv + 40 < 65

Subtract 40 from each side

- pv + 40-40 < 65-40

-pv < 25

Divide each side by -p  (remember to flip the inequality since we are dividing by a negative)

-pv/-p > 25/-p

v > -25/p


7w - 3r = 15

Subtract 7w from each side

7w-7w - 3r = 15-7w

-3r = 15-7w

Divide by -3

-3r/-3 = (15-7w)/-3

r = -5 +7/3 w

Taylor wants to have pool party. Party pools charges $250 to reserve a pool for a private party. They also charge $10 per person
chubhunter [2.5K]
Taylor can have 12 guests come.

375 - 250 = 125 / 10 = 12.5 but since you cannot have half a person the answer is 12

I hope this helps :)
